电力有源滤波器(APF)是一种重要的谐波及无功动态补偿装置,而控制直流侧电压,保证其稳定是保证电力有源滤波器具有良好补偿性能,实现同时补偿谐波和无功的关键。文章从能量补偿的角度出发,介绍一种新的直流侧电压控制方法。该方法从交流电网中输进合适的有功功率补充电力变换器的功耗,使直流电压恒定不变,使得装置的补偿性能良好。仿真结果证明了方法的有效性。
Active power filter (APF) is an important harmonic and reactive power dynamic compensation device, and control the DC voltage to ensure its stability is to ensure that the active power filter has a good compensation performance, to achieve the same time harmonic compensation and no The key to success From the energy compensation point of view, this paper introduces a new DC voltage control method. The method inputs the appropriate active power from the AC power grid to supplement the power consumption of the power converter so that the DC voltage is constant and the compensation performance of the device is good. Simulation results show the effectiveness of the method.
